And a “rear torque limiter 102”), a cylindrical connecting member 103 connected to the front torque limiter 101, and the like. The support shaft 34a is fixed to the lower case 4 via a fixing pin 104 orthogonal to the front end portion thereof (see FIG. 2). That is, the support shaft 34a is not rotatable.

  Further, although detailed illustrations of the front and rear torque limiters 101 and 102 are omitted, both of them are an inner ring that rotates integrally with the support shaft 34a, a housing on the outside thereof, and an intermediate ring between these inner rings and the housing. And a friction mechanism for generating a predetermined frictional force. In such torque limiters 101 and 102, even if a torque less than a predetermined magnitude acts on the housing against the inner ring that is immovably supported by the support shaft 34a, the housing does not move in the same manner as the inner ring. When a torque greater than a predetermined magnitude acts on the housing, the housing slips and becomes rotatable. Thus, in both the torque limiters 101 and 102, the housing is held immovably unless a torque of a predetermined magnitude or larger is applied.

  In the front torque limiter 101, the housing is connected to the connecting member 103, and the connecting member 103 is engaged with the engaging rib 52 b of the upper right holder part 50. That is, the housing of the front torque limiter 101 is connected to the upper right holder part 50 through the connecting member 103. On the other hand, the rear torque limiter 102 is arranged in a state of being accommodated inside the connecting member 103, and the housing is connected to the lower left holder part 60 at the torque limiter engaging part 62b.

  As described above, the upper right holder portion 50 and the lower left holder portion 60 to which the front and rear torque limiters 101 and 102 are connected respectively rotate in the direction in which the torque acts when a torque of a predetermined magnitude or larger is applied. On the other hand, at other times, the position is maintained at that time.

  The motor in the drive box 12 that drives the opening slider 22 and the motor 91 of the accommodation holder drive mechanism 33 in the upside down device 31 are controlled by a control device having a microcomputer (not shown).

  FIG. 9 shows an opening device 110 that forcibly opens the opening portion that is the opened portion when the opened raw material stick B is turned upside down. The opening device 110 is disposed on the bottom plate of the lower case 4 and below the housing holder 32 (see FIG. 6). The opening device 110 includes two front and rear opening arms (hereinafter referred to as “front opening arms”). 111 ”and“ rear opening arm 112 ”) and a torsion spring 113 that biases both opening arms 111 and 112 in the closing direction. Both the open arms 111 and 112 are each formed in a substantially horizontally long planar shape, and support shafts 4 a and 4 a erected on the bottom plate of the lower case 4 are inserted from below at the left end thereof. Thereby, both the opening arms 111 and 112 are supported rotatably about the corresponding support shaft 4a. Further, the front and rear opening arms 111 and 112 are provided with contact portions 111a and 112a which are in contact with each other in a state where they overlap each other in the left-right direction between the both support shafts 4a and 4a.

  Further, when the accommodation holder 32 is turned upside down, the arm driving portion 55 of the upper right holder portion 50 abuts the right front end portion of the front opening arm 111 so that both the opening arms 111 and 112 are opened. A portion 111b is provided. The torsion spring 113 is attached to the support shaft 4a of the rear opening arm 112, and urges the rear opening arm 112 in the clockwise direction.

  When the opening device 110 configured as described above is in a standby state, as shown in FIG. 10A, the right side portions of both the opening arms 111 and 112 extend in parallel in the left-right direction with a predetermined interval therebetween. Closed. On the other hand, when the storage holder 32 is turned upside down, as shown in FIG. 10 (b), the arm driving portion 55 of the upper right holder portion 50 comes into contact with the opening convex portion 111 b of the front opening arm 111. The front opening arm 111 is rotated clockwise in FIG. Accordingly, the contact portion 111a of the front opening arm 111 presses the contact portion 112a of the rear opening arm 112 to the right against the biasing force of the torsion spring 113, so that the rear opening arm 112 is counteracted. Rotate clockwise. As a result, the right portions of both the opening arms 111 and 112 are in an open state in which the distance gradually increases toward the right.

  As shown in FIGS. 2 and 6, when the raw material stick B whose upper end is opened is turned upside down in the lower case 4 at a predetermined position on the right side of the storage holder 32, the raw material stick B is provided. A guide member 120 is provided for guiding the opening portion. The guide member 120 has an arcuate guide surface 120a that is a predetermined distance away from the rotation axis when the storage holder 32 is turned upside down. Further, the predetermined distance is set to a predetermined length such that when the opened raw material stick B is turned upside down, the end on the opening side is bent.

  Next, with reference to FIG. 11 to FIG. 15, a material G dispensing operation from the material stick B by the material dispensing apparatus 1 will be described. In the standby state of the raw material dispensing apparatus 1, as shown in FIGS. 6 and 8 described above, the accommodation holder 32 of the upside down apparatus 31 is in a state of opening upward just below the input port 11 of the upper case 2. Is retained. In the following description, the rotation direction of each part of the raw material dispensing apparatus 1 will be described in a state when the raw material dispensing apparatus 1 is viewed from the front.

  First, when the raw material stick B is introduced into the inlet 11 from above the raw material dispensing apparatus 1, the raw material stick B falls into the raw material dispensing apparatus 1, and as shown in FIG. It is accommodated in the accommodation holder 32 in a state of being held in a standing posture extending along.

  Next, the motor in the drive box 12 is operated, and the drive cam 13 located at the standby position is rotated halfway. As a result, the opening slider 22 moves to the right, and the predetermined position P of the upper end portion of the raw material stick B is cut and opened as follows.

  FIG. 14 sequentially shows the opening operation of the raw material stick B by the opening slider 22. When the opening slider 22 moves to the right from the standby position shown in FIG. 5A, first, the pressing portion 24a of the pressing slider 24 seals the upper side of the raw material stick B as shown in FIG. In the state where the vicinity of the portion is pressed against the lower end portion of the right side wall 11a of the insertion port 11, it abuts on this. In this case, only the slider body 23 of the unsealed slider 22 can be moved further to the right, while the pressing slider 24 is prevented from further movement.

  In this state, when the slider body 23 of the unsealing slider 22 further moves to the right, the pressing slider 24 is urged more strongly to the right by the two compression springs 25, 25, whereby the right side wall 11 a of the insertion port 11. The upper end of the raw material stick B is firmly sandwiched between the two. And as shown in FIG.14 (c), when the slider main body 23 of the opening slider 22 further moves to the cutting position of the right side, the cutting blade 26 integral with this cuts the predetermined position P of the raw material stick B. . Thereby, the upper end part of the raw material stick B is opened. The cut piece Be cut off from the raw material stick B remains sandwiched between the right side wall 11a of the insertion port 11 and the pressing slider 24 of the opening slider 22 until the opening slider 22 returns to the left standby position. And held in the inlet 11.

  After unsealing the raw material stick B as described above, the motor 91 of the accommodation holder drive mechanism 33 is operated, and the drive shaft 93 rotates about 200 degrees in the clockwise direction. Accordingly, the accommodation holder 32 also rotates about the drive shaft 93 (support shafts 33a and 34a) at the same angle as the center, thereby reversing the raw material stick B whose upper end is opened upside down. Thus, the raw material G is dispensed downward from the raw material stick B (see FIG. 12B).

  Here, the operation of each holder part 40, 50, 60 and 70 and the drive flapper 80 when the accommodation holder 32 rotates will be specifically described. First, when the drive shaft 93 rotates clockwise by about 20 degrees from the standby position shown in FIG. 11A, as shown in FIG. The flapper 80 also rotates about 20 degrees in the clockwise direction. Further, in this case, as the drive flapper 80 rotates, the upper left holder part 70 connected to the drive flapper 80 via the two tension coil springs 86 and 87 also rotates about 20 degrees in the clockwise direction.

  However, in this case, the upper right holder part 50 and the lower left holder part 60 are held in the standby position. As described above, the upper right holder part 50 and the lower left holder part 60 are connected to the front torque limiter 101 and the rear torque limiter 102 of the torque limiter mechanism 34, respectively, and the drive shaft 93 is about 20 degrees from the standby position. This is because the torque acting on the upper right holder portion 50 and the upper left holder portion 60 is not so large before the rotation.

  Therefore, when the drive shaft 93 rotates about 20 degrees clockwise from the standby position, the upper end portion of the main body wall 71 of the upper left holder portion 70 comes into contact with the upper end portion of the main body wall 51 of the upper right holder portion 50, and thereby the raw material stick The upper end portion of B is sandwiched between the upper left holder portion 70 and the upper right holder portion 50. In addition, the convex portion 41a of the main body wall 41 of the lower right holder portion 40 abuts on the lower end portion of the main body wall 61 of the lower left holder portion 60, whereby the lower end portion of the raw material stick B, specifically, the raw material stick B The lower sealing portion F is sandwiched between the lower right holder portion 40 and the lower left holder portion 60.

  When the drive shaft 93 further rotates in the clockwise direction from the above state, the accommodation holder 32 rotates in the clockwise direction integrally with the drive shaft 93 while holding the upper and lower ends of the raw material stick B. In this case, the upper right holder unit 50 and the lower left holder unit 60 connected to the front and rear torque limiters 101 and 102 are respectively set to a predetermined size by the upper left holder unit 70 and the lower right holder unit 40 that rotate together with the drive shaft 93. It is pressed with more torque. For this reason, the upper right holder part 50 and the lower left holder part 60 rotate clockwise together with the upper left holder part 70, the drive flapper 80, and the lower right holder part 40.

  Further, the raw material stick B accommodated / clamped by the accommodation holder 32 while the accommodation holder 32 is rotated as described above has an upper end at the guide member in the lower case 4 as shown in FIG. Guided by 120. More specifically, the storage holder 32 is guided in an angular range in which the storage holder 32 rotates about 90 to 150 degrees clockwise from the standby position. In this case, as shown in the figure, the upper end portion of the raw material stick B, that is, the end portion on the unsealing side is guided in a bent state. Thereby, when the raw material stick B is turned upside down, the raw material G can be prevented from splashing from the opened portion of the raw material stick B.

  FIG. 12A shows a state in which the drive shaft 93 is rotated about 180 degrees clockwise from the standby position, and accordingly, the housing holder 32 is also rotated about 180 degrees clockwise from the standby position. In this case, as shown in the figure, the front and rear contact protrusions 72a and 72a of the upper left holder part 70 are in contact with the front and rear stoppers 4b and 4b (only one is shown in the figure). Thereby, even if the drive shaft 93 further rotates clockwise from the above state, the upper left holder part 70 is prevented from further rotation.

  From this state, when the drive shaft 93 further rotates about 20 degrees in the clockwise direction, the lower right holder part 40 and the drive flapper 80 also rotate about 20 degrees in the clockwise direction. Since the lower left holder part 60 rotates integrally with the lower right holder part 40 while being pressed, the sealing part F of the raw material stick B is held between the lower right holder part 40 and the lower left holder part 60. Kept. On the other hand, the lower right holder 50 rotates integrally with the drive flapper 80 while being pressed through the front wall 82 and the rear wall 83 thereof.

  Thereby, as shown in FIG. 12B, the upper right holder part 50 is separated from the upper left holder part 70, and the holding of the end part on the unsealing side of the raw material stick B by these holder parts 50 and 70 is released. As a result, the raw material G in the raw material stick B is dispensed downward by its own weight and supplied to the cup C or the like below. The cup C is transported in advance to a predetermined position inside the pedestal 5 by a cup transport device (not shown), and transported to a hot water supply position where hot water is supplied after the supply of the raw material G is completed.

  Further, when the storage holder 32 rotates as shown in FIGS. 12A and 12B described above, an opening device 110 disposed below the storage holder 32 causes the end of the raw material stick B to be opened. The part is forcibly opened.

  FIG. 15 shows the opening operation of the raw material stick B by the opening device 110 in order. FIG. 4A shows a state in which the storage holder 32 is rotated about 180 degrees from the standby position, and the upper right holder part 50 approaches the opening device 110. In this case, the opening side end portion of the raw material stick B is sandwiched between the upper right holder portion 50 and the upper left holder portion 70, and the inner surface is closely contacted and closed by the guide in the bent state by the guide member 120. May be in a state. In this case, as shown in FIG. 15A, the distance W between the right end portions of the front opening arm 111 and the rear opening arm 112 of the opening device 110 is equal to the opening side end portion of the raw material stick B in the closed state. It is smaller than the lateral width (length in the vertical direction in the figure) Bw.

  When the upper right holder part 50 moves to the left in accordance with the further clockwise rotation of the storage holder 32 from the above state, the arm drive part 55 of the upper right holder part 50 moves forward as shown in FIG. It contacts the opening convex portion 111b of the opening arm 111 and presses it forward (downward in FIG. 15). As a result, the front opening arm 111 rotates in the clockwise direction with the corresponding support shaft 4a on the left as a fulcrum. In this case, the contact portion 111 a of the front opening arm 111 presses the contact portion 112 a of the rear opening arm 112 to the right against the urging force of the torsion spring 113. As a result, the rear opening arm 112 rotates counterclockwise with the corresponding support shaft 4a as a fulcrum. As a result, the front opening arm 111 and the rear opening arm 112 are opened so that the distance W between the right ends is larger than the lateral width Bw of the raw material stick B. Thereby, even if the width of the opening side of the raw material stick B is widened by closing the opening side end of the raw material stick B, the opening side end portion of the raw material stick B is between the right end portions of the front opening arm 111 and the rear opening arm 112. And move as it is.

  When the upper right holder portion 50 further moves to the left as the accommodation holder 32 is further rotated in the clockwise direction from the above state, the arm driving portion 55 is moved to the front opening arm as shown in FIG. 11 is released from the opening convex portion 111b. As a result, the opened front opening arm 111 and rear opening arm 112 are rotated in the opposite direction to the opened state by the urging force of the torsion spring 113 and return to the original standby position. In this case, the opening side end of the raw material stick B is pressed by both the opening arms 111 and 112 from both sides in the width direction. Thereby, even if the opening side end of the raw material stick B is closed, it is forcibly opened. As a result, the raw material in the raw material stick B is smoothly discharged from the opened opening.

  As described above, after all the raw materials G are dispensed from the raw material stick B and the cup C supplied with the raw materials G is conveyed from the inside of the base 5 to another place (for example, hot water supply position), In the following manner, the empty raw material stick B is discarded from the storage holder 32, and the storage holder 32 is returned to the original standby position.

  Specifically, first, in the state shown in FIG. 12B, the motor 91 of the storage holder drive mechanism 33 rotates in the opposite direction to that of the above-described reverse rotation of the storage holder 32, thereby causing the storage holder 32 to rotate counterclockwise. Rotate in the direction.

  FIG. 12C shows a state in which the drive shaft 93 is rotated about 20 degrees counterclockwise in the state shown in FIG. In this case, along with the rotation of the drive shaft 93, the lower right holder part 40 and the drive flapper 80 integrally rotate about 20 degrees counterclockwise, while the upper right holder part 50 and the lower left holder part 60 The stationary state is maintained by the action of the limiter 101 and the rear torque limiter 102. Thereby, the holding of the raw material stick B by the main body walls 41 and 61 of the lower right holder part 40 and the lower left holder part 60 is released. As a result, the empty raw material stick B after the raw material G is dispensed falls by its own weight and is disposed below the storage holder 32.

  Thereafter, the drive shaft 93 further rotates about 200 degrees in the counterclockwise direction, so that the housing holder 32 also moves from the state shown in FIG. 12C to the state shown in FIG. Rotate degrees. In this case, the lower right holder part 40, the upper left holder part 70 and the drive flapper 80 of the storage holder 32 rotate integrally with the drive shaft 93. On the other hand, the lower left holder part 60 is engaged with the lower right holder part 40 and the drive flapper 80 by engagement with the stopper 42a of the lower right holder part 40, and the upper right holder part 50 is engaged with the stopper 83d of the drive flapper 80. Rotates together.

  In this state, the motor of the drive box 12 that drives the opening slider 22 for opening the raw material stick B is actuated again, and the drive cam 13 that has been half-rotated from the standby position is again half-rotated to return to the standby position. . Accordingly, the opening slider 22 returns from the state shown in FIG. 14C to the standby position shown in FIG. Further, in this case, the cut end Be of the raw material stick B held in the insertion port 11 is the right side surface (the main body wall 51 of the upper right holder portion 50 and the lower right holder portion 40) of the accommodation holder 32 shown in FIG. , 41, 41, 41, 41, 41, 41, 41, 41, 41, and the like, as well as the empty raw material stick B that has already been discarded.

  Thus, after discarding the cut end Be, the drive shaft 93 is rotated about 40 degrees in the clockwise direction. Accordingly, as shown in FIG. 13B, the lower right holder part 40, the upper left holder part 70 and the drive flapper 80 of the storage holder 32 rotate about 40 degrees in the clockwise direction integrally with the drive shaft 93.

  On the other hand, the lower left holder part 60 and the upper right holder part 50 are kept stationary by the action of the front torque limiter 101 and the rear torque limiter 102 until the lower right holder part 40 and the drive flapper 80 rotate 20 degrees clockwise. Maintained. Then, when the lower right holder part 40 and the upper left holder part 70 are further rotated 20 degrees in the clockwise direction, the lower left holder part 60 and the upper right holder part 50 are pressed by these holder parts 40 and 70, and FIG. ) To the state shown in FIG. 5B, that is, the main body walls 51 and 61 of the upper right holder part 50 and the lower left holder part 60 are in a substantially vertical posture.

  Thereafter, the drive shaft 93 is rotated about 20 degrees counterclockwise. As a result, as shown in FIG. 13C, the lower right holder part 40 and the upper left holder part 70 integrally rotate with the drive shaft 93 about 20 times in the counterclockwise direction and return to the standby position.

  According to the raw material dispensing apparatus 1 described in detail above, the raw material stick B introduced from the insertion port 11 is held in an upright position by being accommodated in the accommodation holder 32, and the upper space portion S is opened at the time of opening. Since the cutting is performed by the cutting blade 26 of the opening slider 22, it is possible to prevent the raw material G from adhering to the cutting blade 26. Thereby, unlike the conventional case where the cutting condition of the cutter is reduced due to the adhesion of the raw material, it is possible to ensure a good cutting condition of the cutting blade 26 over a long period of time, thereby stabilizing the raw material G from the raw material stick B. Can be paid out.

  Further, when the raw material stick B whose upper end is opened is turned upside down, the space portion S is sandwiched between the upper right holder part 50 and the upper left holder part 70, so that the raw material G is fed into the raw material stick during the turnover. Leakage from B can be suppressed. In addition, when the opened raw material stick B is turned upside down, the end on the opening side is guided in a bent state by the guide member 120, so that the raw material G from the opened portion of the raw material stick B during reversal Spattering can be prevented.

  Moreover, after releasing the raw material G from the raw material stick B, the empty raw material stick B can be dropped downward by its own weight and easily discarded simply by releasing the holding of the sealing portion F of the raw material stick B.

  Further, in the four holder portions 40, 50, 60 and 70 constituting the accommodation holder 32, the lower right holder portion 40 and the upper left holder portion 70 are rotationally driven by the accommodation holder drive mechanism 33 having the motor 91, and the upper right holder By restricting the rotation of the part 50 and the lower left holder part 60 by the torque limiter mechanism 34 having the front and rear torque limiters 101 and 102, the upper and lower ends of the raw material stick B are sandwiched and released, and the raw material stick B is turned upside down. Can be easily performed. Moreover, since it can carry out with the single motor 91 as a drive source of these operation | movement, the raise of the manufacturing cost of the raw material delivery apparatus 1 can be suppressed.

  When the upper end of the raw material stick B is sandwiched between the upper right holder 50 and the upper left holder 70, the upper left holder 70 is connected to the drive flapper 80. , 87 is urged toward the upper right holder portion 50 side. Thereby, the space part S of the raw material stick B can be pinched more firmly, and it can further suppress that the raw material G leaks out of the raw material stick B during the upside down of the raw material stick B.

  Further, when the storage holder 32 is rotated and the raw material stick B is turned upside down with the upper right holder portion 50 and the upper left holder portion 70 sandwiching the space portion S above the raw material stick B, the upper left holder portion 70 is turned upside down. Is brought into contact with the stopper 4 b of the lower case 4 to prevent further rotation, and the upper right holder part 50 is pressed in a direction away from the upper left holder part 70 by the drive flapper 80. In this way, the holding of the space portion S of the raw material stick B can be easily released simply by rotating the accommodation holder 32 and turning it upside down.

  As shown in FIGS. 17 and 18, the threading arm 135 and the holding arm 136 are configured such that the former 135 is on the lower side and the latter 136 is on the lower side while the support shaft 3 a is inserted into the shaft holes 135 a and 136 a from below. Is arranged on the upper side. Further, two torsion coil springs 137 and 138 for urging both arms 135 and 136 in the counterclockwise direction are provided on the support shaft 3a in an up and down direction above the holding arm 136.

  The lower torsion coil spring 137 (the torsion spring for the thread cutting arm) is for the thread cutting arm 135, the upper end 137a is locked to a non-illustrated non-illustrated portion, and the lower end 137b is the thread cutting arm. It is latched by 135 spring latching recess 135b. The torsion coil spring 137 biases the thread cutting arm 135 counterclockwise and toward the standby position shown in FIG.

  The upper torsion coil spring 138 (the torsion spring for holding arm) is for the holding arm 136, the upper end 138a is locked to a non-illustrated non-illustrated portion, and the lower end 138b is held to the holding arm 136. Is locked to the spring locking projection 136b. The torsion coil spring 138 biases the holding arm 136 counterclockwise and toward the standby position (holding arm standby position) shown in FIG. The torsion coil spring 138 has a larger urging force than the torsion coil spring 137 for the thread cutting arm 135.

  Next, the opening operation of the raw material stick B by the opening mechanism 131 will be described with reference to FIGS. FIGS. 21A and 24A show the unsealing mechanism 131 in the standby state, and the raw material stick B extends in the vertical direction when the raw material stick B is inserted into the insertion port 11. The state immediately after being accommodated in the accommodation holder 32 while being held in the standing posture is shown. From this state, by executing the same control as the control in the raw material dispensing apparatus 1 described above, the predetermined position P of the upper end portion of the raw material stick B is cut and opened as follows.

  First, the motor in the drive box 12 operates, and the drive cam 13 starts to rotate counterclockwise from the standby position shown in FIG. As a result, as shown in FIG. 5B, the drive slider 132 moves to the right, and the tip of the thread cutting arm 135 is moved to the torsion coil spring 137 via the pressing surface 143a of the arm pressing portion 143. By pushing rightward against the urging force, the threading arm 135 rotates clockwise. In this case, the pressing slider 133 positioned below the driving slider 132 is connected to the driving slider 132 via the tension coil spring 134 and thus moves to the right together with the driving slider 132.

  Next, when the driving cam 13 further rotates counterclockwise, the driving slider 132 and the pressing slider 133 move to the right as shown in FIGS. The predetermined position P of the upper end portion of the raw material stick B is pressed against the right edge portion of the opening 21a of the top plate 21 through the pressing surface 133b. Further, in this case, the upper end portion of the raw material stick B is firmly sandwiched in such a state that the minute protrusion 133c of the pressing slider 133 fits into the minute recess 21b at the right edge of the opening 21a.

  Next, when the drive cam 13 further rotates counterclockwise and the drive slider 132 moves further to the right, the pressing slider 133 biased by the tension coil spring 134 is opened as shown in FIG. Further abuts against the right edge of 21a, preventing further movement. Further, in this case, the thread cutting arm 135 pressed by the arm pressing portion 143 of the drive slider 132 holds the upper end portion of the raw material stick B between the holding arm 136. More specifically, almost half of the raw material stick B in the width direction (vertical direction in FIG. 22) is sandwiched between the clamping surface 135c of the threaded arm 135 and the clamping surface 136c of the holding arm 136.

  Next, when the drive cam 13 further rotates counterclockwise and the drive slider 132 moves further to the right, as shown in FIG. 23A, the thread cutting arm 135 is added to the torsion coil spring 137 and the holding arm. The holding arm 136 is pressed to rotate clockwise against the biasing force of the torsion coil spring 138 for use. That is, the thread cutting arm 135 rotates in the clockwise direction integrally with the holding arm 136 while the upper end portion of the raw material stick B is sandwiched between the threading arm 135 and the holding arm 136. Thus, at the upper end of the raw material stick B, threading is started from the side far from the support shaft 3a.

  Then, when the drive cam 13 further rotates counterclockwise and the drive slider 132 moves further to the right, the threading arm 135 and the holding arm 136 further move as shown in FIGS. It rotates clockwise, whereby the threaded piece Be is separated from the raw material stick B and its upper end is opened.

  As described above, after the upper end portion of the raw material stick B is opened by being threaded, the raw material discharging apparatus 1A discharges the raw material G in the same manner as the raw material discharging apparatus 1 described above. The drive cam 13 at the position shown in (b) further rotates halfway counterclockwise and returns to the standby position. As a result, the drive slider 132, the pressing slider 133, the threading arm 135, and the holding arm 136 are also returned to the standby position shown in FIG.

  As described in detail above, according to the present embodiment, the drive box 12 having a single motor moves the drive slider 132 to the right, so that the predetermined position P of the upper end portion of the raw material stick B is fixed. While holding, the upper end portion of the raw material stick B is threaded in a state where the upper end portion of the raw material stick B is sandwiched between the thread cutting arm 135 and the holding arm 136. Thus, since the upper end portion of the raw material stick B is cut without using a cutting blade, the raw material stick B is opened more hygienically without causing a problem that the raw material adheres to the cutting blade. be able to. This makes it possible to stably open the raw material stick B over a long period of time, unlike the conventional case where the cutting condition of the cutter is reduced due to the adhesion of the raw material.

  In addition, this invention can be implemented in various aspects, without being limited to the said embodiment described. For example, in the embodiment, the pressing slider 133 and the threaded arm 135 are driven by moving the driving slider 132 horizontally by using a single motor of the driving box 12 as a driving source. However, the present invention is not limited, and other suitable mechanisms for transmitting the power source of the motor of the drive box 12 to the pressing slider 133 and the threading arm 135 may be used.

  In addition, the detailed configuration of the raw material dispensing apparatuses 1 and 1A and the unsealing mechanism 131 shown in the embodiment are merely examples, and can be appropriately changed within the scope of the present invention.
